Ghetto fabulous templating system. More ghetto than fabulous.

ba-ghettotmpl.js

// Ghetto fabulous template system for replacing values in strings. If {{.foo}}
// or {{.bar[0].baz}} is encountered (leading dot), attempt to access properties
// of data object like `data.foo` or `data.bar[0].baz`. Alternately, if {{foo}}
// or {{bar("baz")}} is encountered (no leading dot), simply evaluate `foo` or
// `bar("baz")`. If an error occurs, return empty string. @rworth++
