 * Searches for a member definition given its name `memberName' as a string.
 * memberName may also include a (partial) scope to indicate the scope
 * in which the member is located.
 *
 * The parameter `scName' is a string representing the name of the scope in 
 * which the link was found.
 *
 * In case of a function args contains a string representation of the 
 * argument list. Passing 0 means the member has no arguments. 
 * Passing "()" means any argument list will do, but "()" is preferred.
 *
 * The function returns TRUE if the member is known and documented or
 * FALSE if it is not.
 * If TRUE is returned parameter `md' contains a pointer to the member 
 * definition. Furthermore exactly one of the parameter `cd', `nd', or `fd' 
 * will be non-zero:
 *   - if `cd' is non zero, the member was found in a class pointed to by cd.
 *   - if `nd' is non zero, the member was found in a namespace pointed to by nd.
 *   - if `fd' is non zero, the member was found in the global namespace of
