Create an easy to use gitian building script

I've written a script that automates the setup and building of binaries with gitian. All of the commands are pulled from various documentation on gitian building.

+Usage: $scriptName [-c|u|v|b|s|B|o|h|j|m|] signer version
+
+Run this script from the directory containing the bitcoin, gitian-builder, gitian.sigs, and bitcoin-detached-sigs.
+
+Arguments:
+signer          GPG signer to sign each build assert file
+version		Version number, commit, or branch to build. If building a commit or branch, the -c option must be specified
+
+Options:
+-c|--commit	Indicate that the version argument is for a commit or branch
+-u|--url	Specify the URL of the repository. Default is https://github.com/bitcoin/bitcoin
+-v|--verify 	Verify the gitian build
+-b|--build	Do a gitiain build
+-s|--sign	Make signed binaries for Windows and Mac OSX
+-B|--buildsign	Build both signed and unsigned binaries
+-o|--os		Specify which Operating Systems the build is for. Default is lwx. l for linux, w for windows, x for osx
+-j		Number of processes to use. Default 4
+-m		Memory to allocate in MiB. Default 2000
+--kvm           Use KVM instead of LXC
+--setup         Setup the gitian building environment. Uses KVM. If you want to use lxc, use the --lxc option. Only works on Debian-based systems (Ubuntu, Debian)
+-h|--help	Print this help message
