##Getting Started payslip-generator exports a single class, PayslipGenerator.

var PayslipGenerator = require('payslip-generator');
var payslipGenerator = new PayslipGenerator(taxTable);

taxTable is an array of taxTble items. Each item in taxTable must have following fields:

• minSalary: A mandatory number (>= 0)
• maxSalary: A mandatory number (>= 0)
• baseTax: A mandatory number (>= 0)
• taxPerDollar: A mandatory number (>= 0 & < 1)

An example of taxTable array:

[
  {
    "minSalary": 0,
    "maxSalary": 18200,
    "baseTax": 0,
    "taxPerDollar": 0
  },
  {
    "minSalary": 18201,
    "maxSalary": 37000,
    "baseTax": 0,
    "taxPerDollar": 0.19
  },
  {
    "minSalary": 37001,
    "maxSalary": 80000,
    "baseTax": 3572,
    "taxPerDollar": 0.325
  },
  {
    "minSalary": 80001,
    "maxSalary": 180000,
    "baseTax": 17547,
    "taxPerDollar": 0.37
  },
  {
    "minSalary": 180001,
    "maxSalary": 0,
    "baseTax": 54547,
    "taxPerDollar": 0.45
  }
]

##PayslipGenerator.prototype.generate() .generate() function expects following params:

• firstName: mandatory string param
• lastName: mandatory string param
• annualSalary: mandatory positive number
• superRate: mandatory positive number
• paymentPeriod: A calendar month

var PayslipGenerator = require('payslip-generator');
var taxTable         = require('./tax-table.json');
var payslip          = new PayslipGenerator(taxTable);
var result           = payslip.generate('Mehdi', 'Valikhani', 60500, 9, 'March');

.generate() function is a syncronous method, it may return an error or a payslip generator. To make life easier we always return an array with maximum of two item.

• err: An instance of Error class
• payslipObject: Payslip object

###An example of payslip object

{
  "firstName"      : "David",
  "lastName"       : "Rudd",
  "paymentPeriod"  : "March",
  "grossIncome"    : 5004,
  "incomeTax"      : 922,
  "netIncome"      : 4082,
  "superAnnuation" : 450
