check_version() {

Tests for a minimum version level. Compares to version numbers and forces an
exit if minimum level not met.
NOTE: This test will fail on versions containing alpha chars. ie. jpeg 6b
usage: check_version "2.6.2" "`uname -r`" "KERNEL"
check_version "3.0" "$BASH_VERSION" "BASH"
check_version "3.0" "`gcc -dumpversion`" "GCC"
input vars: $1=min acceptable version
$2=version to check
$3=app name

modifies: --
returns: nothing
on error: write text to console and dies
on success: write text to console and returns
