===========

Taxman caches values for you.

Introduction

------------

This module was inspired by the need for an easy way to asynchronously compute a value once, but use it in multiple

places.

Examples

--------

    var taxman = require('taxman')

    

    // Create a taxman to compute the value

    var computation = taxman(function(callback) {

        console.log("Doing lots of hard work...")

        var x = 3 * 5

        callback(null, x)

    })

    // Get the computation value (this first call will start the computation, synchronously, in this case)

    computation(function(error, value) {

        if (error) {

            console.error("1a: computation failed")

        } else {

            console.log("1a: success! result = ", value)

        }

    })

    // Get the computation value again (retrieves cached value)

    computation(function(error, value) {

        if (error) {

            console.error("1b: computation failed")

        } else {

            console.log("1b: success! result = ", value)

        }

    })

    // Reset the cache

    computation.reset()

    // Get the computation value (this will re-compute the value)

    computation(function(error, value) {

        if (error) {

            console.error("1c: computation failed")

        } else {

            console.log("1c: success! result = ", value)

        }

    })

Outputs:

    Doing lots of hard work...

    1a: success! result =  15

    1b: success! result =  15

    Doing lots of hard work...

    1c: success! result =  15
