You have to see what is the tag for the helper in app/code/community/Inic/Catalog/etc/config.xml. Search for <helpers>. Most probably it is:

    <helpers>
        <inic_catalog>
            <class>Inic_Catalog_Helper</class>
        </inic_catalog>
    </helpers>

then you have to use:

Mage::helper('inic_catalog/product_view')->gevalnow();

You have to replace inic_catalog with the string from the config.xml (below <helpers> tag).

Magento 1.7 – Fix Fatal Error: Class ‘Mage_Rms_Helper_Data’ Not Found

You configured your helper class like this.

<helpers>
    <rms>
        <class>NewHope_Rms_Helper</class>
    </rms>
</helpers>

So when you request you helper class with Mage::helper('rms'), Magento will trace your module, since it defines the helper alias name rms and then pick class name associate with it. So in this case, Magento has NewHope_Rms_Helper. The next step magento checks, whether you requested in particular helper class name. For example, if you were requested a helper class like Mage::helper(rms/example), then magento will append this example part to the class that already picked from your configuration and thus completes the class generation process(Here the class would be NewHope_Rms_Helper_Example). However if we didn't specify any specific helper name, then by default, Magento assumes this class name as Data. So in your case, Magento forms final helper class as NewHope_Rms_Helper_Data.

The name of the class is an indication to the location where that class should be defined. That means Magento will now look for your helper in app/code/local/NewHope/Rms/Helper/Data.php. If it is not present there, it will look in app/code/community/NewHope/Rms/Helper/Data.php. Then again in app/code/core directory and then again in lib directory. In your case, Magento can't find the helper class. So as a result it will throw an error.(Note location generated is NewHope\Rms and not NewHope\RmsUpdate).

So the configuration that you need here is

<helpers>
    <rms>
        <class>NewHope_RmsUpdate_Helper</class>
    </rms>
</helpers>

So this will generate a class NewHope_RmsUpdate_Helper_Data and thus first it will look in the location app/code/local/NewHope/RmsUpdate/Helper/Data.php. The file content should look like this.

<?php
class NewHope_RmsUpdate_Helper_Data extends Mage_Core_Helper_Abstract
{
}

Hope that will give you an idea on what is really happens in the backside

Magento – How to override Magento model file that extends PHP class

Below a simple example of how to override a model from one module within another module.

Please take a look at the file app/code/local/Customweb/PostFinanceCw/etc/config.xml for the correct use of the modulename namespace (which I can't read from your question, I used customweb_postfinancecw for now).

You'd have to have a piece of XML like this in your module's config.xml (I named it MyCompany_MyModule, please replace it with your own)

<config>
    <global>
        <models>
            <mycompany_mymodule>
                <class>MyCompany_MyModule_Model</class>
            </mycompany_mymodule>
            <customweb_postfinancecw>
                <rewrite>
                    <ordercontext>MyCompany_MyModule_Model_OrderContext</ordercontext>
                </rewrite>
            </customweb_postfinancecw>
        </models>
    </global>
</config>

Then, in app/code/local/MyCompany/MyModule/Model/, create a file OrderContext.php like this

class MyCompany_MyModule_Model_OrderContext extends Customweb_PostFinanceCw_Model_OrderContext
{

    /* Override methods now */

}

You should name the methods exactly the same as in the original Customweb_PostFinanceCw_Model_OrderContext class to override it's functionality. Also keep in mind to keep the same visibility (public, protected or private).
