/* modified by dandavis to become Mo'stache v0.8.2a
mustache improvements
inspired by dust:
The {SEP} some marker like <hr>, ", ", etc{/SEP} mini-section prints the enclosed block for every value except for the last.
The {INDEX} mini-tag passes the numerical index of the current element to the enclosed block.
my idea, somewhat like angular but not custom code:
{{phone.connectivity.radio | escape }} - any function that outputs stringy things, including eval
EX: {{name|escape|btoa}} // uses global functions
EX: {{|Math.random}} // uses global function
EX: {{name|.bold}} // uses self method (w/o arguments), indidcated by dot prefix
EX: {{name.bold}} // (native method mustache behaviour over-ride)
EX: {{numbers|JSON.stringify}} //uses global path
EX: {{123 * 456 |eval}} // uses expression and eval() for opt-in overloading/active processing
