Subject: Added check for non-alphabetic words
X-Git-Url: https://harishankar.org/repos/?a=commitdiff_plain;h=HEAD;p=getaclue.git

Added check for non-alphabetic words

Added exception and handler for non-alphabetic words in the
creator. This prevents creating words in the grid with numbers
or non-alphabetic symbols.
