Reformat output header columns to fit number of data columns

[ELeeAstro]

Currently the format of the chemistry.dat file header is as follows:

P (bar) T(k) n_ (cm-3) n_g (cm-3) m (u)

I propose removing the space between variables and their units e.g. P (bar) -> P(bar). This allows easier reading of the header and following data (by e.g. numpy) as the number of columns are now equal between the header and data.

Using the correct delimiter ('\t') when reading in the file should be enough, I think. I would also suggest to use pandas when reading in the file because it allows to directly use the header information. So, for example:

import pandas as pd

df = pd.read_table('chemistry.dat', sep=' *\t')

Then you can access the specific data columns by using their names, so for example H2O is addressed as

df['H2O1']

or if you want the data as a numpy array

h2o_data = np.array(df['H2O1'])

Let me know if this works for you or if the header should still be adjusted.

Reading in also works in Numpy when using the correct delimiter, by the way:

data = np.genfromtxt('chemistry.dat', names=True,, delimiter='\t')

I now changed the header format and removed the empty spaces for the C++ and the Python versions.
