Example

from rootloader import tfile

# read file
fid = tfile('myfile.root')

# key values can be accessed as attributes or as keys
# say there's a tree named "tree1". We can access it as
tr = fid.tree1

# or
tr = fid['tree1']

# get a pandas dataframe from the tree (the tree is left unaltered)
df = tr.to_dataframe()

# try to convert all file contents to pandas dataframes, and replace keys with these dataframes
fid.to_dataframe()
