Implementation of `ODEGeneralSolutionComponent` class that creates a part of a report

[bogumilchilinski]

Propose the code for general solution prediction method of solving ODEs. Prepare a new ReportComponent for reports.

[Danielstryjewski]

The code was checked with the following call:

from dynpy.utilities.components.ode.en import ODEGeneralSolutionComponent
from dynpy.models.odes.linear import LinearFirstOrder

ode_test = LinearFirstOrder.from_reference_data()

ODEGeneralSolutionComponent(ode_test);
