• Remove use of variables that aren't really needed in InitCode
• Eliminate the use of strings.Builder overhead
  • Also removes import of strings package
  • Speeds execution of buildSchema by 35%+
  • Significant decreased memory usage by buildSchema

The refinement of buildSchema is probably not really useful when
used from a command line utility, but if someone was to use this
package as part of a REST API or other utility that performs this
work repeatedly, it helps with memory use and runtime overhead.
