Installing daru on a fresh system

[lokeshh]

There are couple of problems faced after installing Daru on a new computer.

• It produces some NameError.

NameError: uninitialized constant Daru::Accessors::ArrayWrapper::Forwardable

The above error goes away on installing reportbuilder gem

• Second is this one:

2.3.0 :002 > dv = Daru::Vector.new [1, 2, 3]
 => #<Daru::Vector(3)>
   0   1
   1   2
   2   3 
2.3.0 :003 > dv.to_s
NameError: uninitialized constant Daru::Vector::ERB

This one is the cause of build failure in Statsample here.

It goes away after one do require 'erb'.

The issue can be reproduced doing the following:

1. rvm remove 2.3.0
2. rvm install 2.3.0
3. gem install daru
4. require 'daru'

Here are all error messages in detail.
Can we include a test in Travis CI to check for such things in future?

This should not have anything to do with reportbuilder. ArrayWrapper uses the Forwardable module.

I changed that line to ::Forwardable and added a require 'forwardable and it worked.

It goes away after one do require 'erb'.
Did that too. Pushing in a while.

Need to think of a foolproof way of testing deployment of daru on new systems hmmm....

Should be fixed with be6cea4
