# Echo printing utility

# README
# Installation: Run `source Echo.sh "PREFIX"`
# Use command `Echo [FLAGS] MSG` instead of `echo [FLAGS] MSG` to print out your
# PREFIX on every line
# Overwrite prefix with `EchoPrefix=PREFIX` to change prefix
# Inside your print messages, insert `$(EchoColor COLOR)` to change color
# By default, `$(EchoColor)` will reset text color to default

# Boolean class
True=0
False=1

   return $1
