This nifty little program adds a CR/LF at the end of every
file with the given extension within the directory tree
from where it was called (i.e. recurses in sub-directories).

Syntax:
    add_crlf [ext1] [ext2] [...]

Extensions are given in the form:
    .cpp .h .txt (no asterisk at the beginning)
