Checks if a function is a S3/UseMethod generic function

Checks if a function is a S3/UseMethod generic function.

## Default S3 method:
isGenericS3(fcn, ...)

`fcn`	A `function` or a `character` string.
`...`	Not used.

A function is considered to be a generic S3/UseMethod function if its body, that is the source code, contains the regular pattern "UseMethod[(]".

Returns TRUE if a generic S3/UseMethod function, otherwise FALSE.
