Draft outline of the Higgs section for Snowmass CLIC report

In this draft the various energy stages are not treated as separate chapters, but integrated into the physics program.  

Introduction
- The central importance of studying Higgs boson (it is the science of our times)
- Current state of affairs for Higgs boson physics
- Expectations for LHC capabilities (not assuming HL-LHC or HE-LHC upgrades)
- Overview of capabilities at staged e+e- machine: energies, luminosities, polarization, etc.
- Clear statements of value added with e+e- machine

Higgs Boson mass, width and total production cross-section
- Measuring Higgs boson mass
- Determination of the Higgs boson width
- Higgs boson total cross-section determinations

Higgs boson decays and couplings to Standard Model 
- Expectations of decay branching fractions in the SM
- Measurement of sigma*Br into b quarks
- Measurement of sigma*Br into W bosons
- Measurement of sigma*Br into Z bosons
- Measurement of sigma*Br into muons
- Measurement of sigma*Br into c quarks
- Measurement of sigma*Br into gluons
- Measurement of the ttH rate
- Measurement of the Higgs self-coupling through HH production
- Extracting couplings (key table of parameter determination/couplings here -- combined fit procedure?)

Higgs boson properties and physics beyond the SM
- Sensitivity to invisible decay width
- Rare, exotic Higgs decay sensitivities (e.g., Higgs decays to light 'axion'-like particles, etc.)
- Sensitivities to Higgs boson mixing with other Higgses (extra doublets or singlets mixed in)
- New production mechanisms of the Higgs boson (Higgs as decay product of heavier state)

Conclusion
- Summary of main points of chapter
- Re-statement of value added with the CLIC collider
