+/**
+ * Initializes and compiles the theme according to the ruleset
+ *
+ * @param {Object[]} inputRuleset - set of rules to compile theme against. Acts as an override to
+ *   component default rulesets
+ * @param {string} ultimateBackgroundColor - Color that will be the "final" background for
+ *   calculating contrast ratios and making text automatically accessible. Really used for cases when
+ *   stuff is transparent.
+ * @param {boolean} debug - print out debug information in console, mostly just performance stuff
+ * @param {boolean} liteMode - use validInnerComponentsLite instead of validInnerComponents, meant to
+ *   generatate theme previews and such that need to be compiled faster and don't require a lot of other
+ *   components present in "normal" mode
+ * @param {boolean} onlyNormalState - only use components 'normal' states, meant for generating theme
+ *   previews since states are the biggest factor for compilation time and are completely unnecessary
+ *   when previewing multiple themes at same time
+ * @param {string} rootComponentName - [UNTESTED] which component to start from, meant for previewing a
+ *   part of the theme (i.e. just the button) for themes 3 editor.
