Panda 0.15.1 matplotlib 1.4.2 setting boxplot heading/subheading
Hi, 

the heading and subheading in the DataFrame.boxplot and DataFrame.hist are generated automatically. I have several issues here.

1) Would like to have the option to turn it on/off/modify content.
2) Default distance between subheading and heading should be larger
3) Default generation of heading/subheading should be consistent

At the moment the functions generate different headings/subheadings.

regards
