Parameters:

cs - the CharSequence to be processed

ignoreCase - whether or not to be case insensitive

thisStart - the index to start on the cs CharSequence

substring - the CharSequence to be looked for

start - the index to start on the substring CharSequence

length - character length of the region

Returns:

whether the region matched
