Primitive automated spell-checking of markdown using sed and ispell

(Why yes, this is a niche post!) Right now this is just a shell script, but it could easily be added to the build process so that a typo (or a new word missing from the project words list) would break the build - no more bad documentation!

#the below regexps remove
# - basic HTML tabs
# - heading hashes
# - code samples
# - inline code
# - URLs
#from markdown-formatted code, as a prelude to spellchecking
