Fix code style

[sfe-SparkFro]

From @gigapod in #8:

for the internal classes/templates, can we move to a CamelCase class name, not the YELLING_AT_YOU format? Minor, but more approachable and modern.

Also, should run everything through a formatter

Also from @gigapod in #10:

File should use 4 char spacing, not 2
