close #13
Fix typos in README
fix #16
Fix polynomials with rational coefficients.

1. Get rid of eps check in constructor. Many types don't have an eps method.
2. Find more precise types for results of division.
restore usage of eps to trim leading coefficients
Set up travis integration.
Added support for optional variable parameter in constructor. Added string function to get string representation without 'Poly(...)' appended. Printed representation now uses corresponding variable, formats coefficients up to 4 decimal places, and removes uncecessary coefficients and powers (i.e. x^1 now is just x). All operations involving two polynomials now must have the same 'var' attribute. Added tests for new functionality, and updated the README.
Changed var attribute to string type, rolled back change to output formatting. Added eps function for complex types
Changed var attribute to be of type Symbol. Added constructors for String and Char as well. Added tests to validate constructors
simplify ctors, printing; fix Poly string representation
