Method to locate a convolution function for the given w-term index and PA value.

This is the top level function that must be used by the clients. This uses searchConvFunction() and loadFromDisk() methods and the private methods to return a convolution function.

Returns CFDefs::NOTCACHED if the convolution function was not found in the cache, CFDefs::MEMCACHE or CFDefs::DISKCACHE if the function was found in memory or disk cache respectively.
