Version 1.0.0

In this version:
Chart.py was renamed to pichart.py.

Now contains three classes:

• Chart: The main class for creating charts
• Card: A simple card that contains just a title and can be styled just like a chart
• Container: The container makes laying out charts really simple, just add the charts using add_chart(Chart) and then specify the number of columns, or leave it blank if you just want rows
